[osg-users] Caustics for UnderWater Effect by GLSL

Hi All, I have found a good Thesis(2007) about creation UnderWater effects with using OpenSceneGraph and GLSL and I want to share with you. It was developed by Philippe APERY from University of HULL. You can download this thesis from http://apery.tesseract.fr/thesis.pdf Best Regards. Umit Uzun

[osg-users] Caustics for UnderWater Effect by GLSL

Hi All, I have researched and decided to create my underwater caustics effect by GLSL. I have been studying GLSL for a week and grasp the main structure Shading technique. But when I search the osg mail list and shader samples I couldn't find using texturing models by GLSL exxamples. So I could't

Re: [osg-users] Caustics for UnderWater Effect

Hi Robert, Thanks for reply. I am looking for osgTexture3D for create caustics on terrain surface with alpha value between 0.0-0.5 When I texture I want to see terrain surface with caustics but I can only see textures with different state like transparance and opaque version in sliding. What can

[osg-users] Caustics for UnderWater Effect

Hi All, I have 30 textures for *causticshttp://www.dualheights.se/caustics/CausticsAnim1.avi *. I want to make a underwater effect so have to alpha blend texture to terrain surface which was created with VirtualPlanetBuilder. My question is, how should I animate these textures on the terrain?

Re: [osg-users] Caustics for UnderWater Effect

Hi Umit, I'd use a Texture3D to animate through the images (see osgtexture3D for an example), or if you don't need blending ImageSequence would work on a Texture2D (see osgimagesequence for an example). Texture2DArray is also possible, but it's only supported on latest hardwares/drivers. Robert.
